Author: marius Date: Sun Jan 29 12:58:07 2012 New Revision: 230741 URL: http://svn.freebsd.org/changeset/base/230741 Log: MFC: r228211 It doesn't make much sense to check whether child is NULL after already having dereferenced it. We either should generally check the device_t's supplied to bus functions before using them (which we seem to virtually never do) or just assume that they are not NULL. While at it make this code fit 78 columns.
